But now, scientists from the lab of Fabrizio Carbone at EPFL have demonstrated that it is possible to use light to dynamically twist an individual electron's wave function.  The scientists used the quantum nature of the electron-light interaction to separate the electron-reference and electron-imaging beams in energy instead of space.  A holographic acoustic tweezers (HAT) system has been used to suspend up to 25 objects in mid-air simultaneously.  Holography is a powerful tool that can reconstruct wavefronts of light and combine the fundamental wave properties of amplitude, phase, polarization, wave vector and frequency.  Physicist Artem Rudenko from Kansas State University and his colleagues pondered how to improve the images of viruses and microparticles that scientists get from X-rays.  A team of materials scientists from Penn State, Cornell and Argonne National Laboratory have, for the first time, visualized the 3-D atomic and electron density structure of the most complex perovskite crystal structure system decoded to date.  Hydrogen-powered electronics, travel, and more may be a step closer thanks to the work of a collaborative team of scientists in Japan.  "The realization of such all-optical single-HYPERLINK "https://phys.org/tags/information+processing/" information processing," says Tanji-Suzuki.  Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules.  A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues.
